23. In quantum rings of finite width, deviations of the strict fractional periodicity appear and the ground-state envelope is not constant but grows with the magnetic field [see Ref. or J. I. Climente, J. Planelles, and J. L. Movilla, Phys. Rev. B PRBMDO 0163-1829 10.1103/PhysRevB.70.081301 70, 081301 (R) (2004)].
24. On the other hand, the finite width of the ring is crucial for the description of excitons [see, for instance, J. I. Climente, J. Planelles, and W. Jaskólski, Phys. Rev. B PRBMDO 0163-1829 10.1103/PhysRevB.68.075307 68, 075307 (2003)];
25. in the strictly one-dimensional ring, the electron and the hole would be point localized with an infinite binding energy [R. Loudon, Am. J. Phys. AJPIAS 0002-9505 10.1119/1.1934950 27, 649 (1959)].
